Coastal erosion is the natural process in which shoreline material is lost from coastlines due to friction forces caused by waves, ocean currents, or others over time. In addition, this problem affects countries that have access to the sea, since erosion not only erodes beaches, but also harms urban development, preventing human activities such as construction or recreation from taking place. For this reason, the use of artificial structures such as breakwaters is proposed to prevent erosion on the coasts. Breakwater allows to counteract waves erosion. There are several types with different composition and morphology. These structures are built between the sea and coast, and their function is to absorb waves energy, decreasing their height and lightening waves. Consequently, this process in a prolonged period generates sedimentation of coastal material on beaches due to decrease in waves forces. In Peru, this problem occurs on various beaches, being in this study case La Herradura beach located in Chorrillos Bay in Lima, Peru. This beach has been eroded and has lost a total of approximately 30m of shoreline. Reason for which breakwater simulations were carried out in a computational numerical software (Delft 3D). First, 2 breakwater systems were simulated, then a third model was proposed with improvements in its design, obtaining more favorable results. Finally, a comparison was made between the proposed model with a conventional straight breakwater, the result of the third proposed model being even higher, reducing the height of the waves by up to 97.85%.
